Abstract: The specification discloses a monitor, a system, and a method for monitoring the electrolyte level in a cell of a multi-cell battery. The system may be powered by leads attached across any one or more cells of the battery. The system includes an electrically conductive probe, having its own wire, that may be installed in any battery cell. The probe is current sampled to provide one or more signals used to determine if the probe is in physical contact with the electrolyte (indicating acceptable electrolyte level). The probe may be sampled as a cathode and as an anode. The probe may be sampled using PWM (pulse width modulation). The probe may be sampled using current limiting.

Abstract: A locking fastener includes a thermoplastic fastener body, a locking coil, and a support collar. The fastener body defines a cylindrical cavity and a radially extending slot communicating with the cavity. The support collar has an arcuate portion and first and second tabs extending radially outward from the arcuate portion. The support collar is disposed within the fastener body with the arcuate portion adjacent the cavity wall and the tabs extending into the slot. The locking coil has a helical portion and first and second tangs extending radially outward from the helical portion. The helical portion of the locking coil is positioned within the support collar, and the first and second tangs extend into the slot and between the first and second tabs.

Abstract: A coupling element or attachment device mechanically and electrically mates a fuel injector to a plastic fuel rail. The attachment device electrically couples the male electrical connector to integral wiring within the fuel rail. The attachment device is preferably slidably engaged upon ribs or grooves on the fuel rail and slidably engaged to the male electrical connector. The device secures the fuel injector to the fuel rail without the necessity of a metal clip. The device may be manufactured from a unitary plastic molding. A plurality of attachment devices may be utilized to secure two or more fuel injectors to the fuel rail.

Abstract: A fuel tube is attached to a fuel rail by a novel one-piece plastic clip comprising an integral fork for trapping a flange of the fuel tube against withdrawal from the fuel rail hole in which it is received and also comprising integral catches at the sides for catching on notches in the wall of the fuel tube.
